cPdfWriter Image Graph Driver 0.2.2

cPdfWriter is a PHP5 class for exporting PDF documents based on TCPDF, FPDF, and other related scripts.
Installation instructions:
To use this driver copy it in the directory of Image_Canvas.
This should normally be "/usr/share/pear/Image/Canvas/" but it might differ slightly for you.
Then use it just as you would use any Image_Graph canvas, i.e.:
< ?php
include_once Image/Graph.php;
include_once Image/Graph/Driver.php;
$Canvas =& Image_Canvas::factory(CPDFWRITER,array(width => 600,height => 400));
$Graph =& Image_Graph::factory(graph, &$Canvas);
